Results recalculate instantly on every keystroke. Nothing you type is transmitted.
What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: Assets of $774,400 against liabilities of $342,500 give a net worth of $431,900. But only $114,900 of those assets are liquid, and after non-mortgage debt the genuinely accessible figure is $60,400 — 14% of the headline. A 10% fall in house prices would remove 9.6% of the total.
Formula
The second line is the one that matters under stress: retirement accounts carry penalties and property takes months to sell, so neither is available for an emergency.
Worked Example
- Total the assets. $18,400 + $96,500 + $212,000 + $415,000 + $23,000 + $9,500 = $774,400.
- Total the liabilities. $288,000 + $14,800 + $31,200 + $6,400 + $2,100 = $342,500.
- Take the difference. $431,900 of net worth.
- Isolate what is liquid. Cash and investments total $114,900 — just 14.8% of assets.
- Deduct the non-mortgage debt. $114,900 − $54,500 = $60,400 of genuinely accessible net worth.
Analyst's note. A single number hides the important structure here. This household is worth $431,900 on paper but could reach only $60,400 of it without selling a house or breaking into retirement accounts. That is not a criticism — retirement balances and home equity are exactly where long-term wealth should sit — but it explains why households with substantial net worth still experience acute cash stress. The 10% property shock is worth noting too: one asset class swings 9.6% of the total, which is concentration risk by any other name.

- Free, unmetered and free of affiliate incentives.
Where it stops
- Generalised assumptions cannot capture every individual circumstance.
- Jurisdiction-specific rules and mid-year changes may not be reflected.
- A model output is not a substitute for a professional review of your position.
Practical Use Cases
Tracking progress rather than a single snapshot
Net worth is most useful as a trend. Record it quarterly and watch the direction, since any single reading is dominated by property and market valuations you do not control. Project the trajectory with the Investment Calculator.
Stress-testing your liquidity
If liquid net worth is thin, the household is fragile regardless of the headline. Compare the accessible figure against the reserve you need using the Emergency Fund Calculator.
Deciding whether to overpay the mortgage
Overpaying converts liquid assets into illiquid equity — a guaranteed return at the cost of access. Weigh the interest saved via the Extra Payment Mortgage Calculator against the flexibility given up.
Methodology & Editorial Standards
Assets are grouped by liquidity rather than by type, because accessibility under stress is the distinction that matters. Retirement accounts are classified as illiquid despite often being large, since early withdrawal generally triggers tax and penalties; taxable investments are treated as liquid though selling may realise capital gains tax and can coincide with a market fall. Liquid net worth deducts all non-mortgage debt, since those balances are callable or short-dated, while the mortgage is matched against the property it secures. Property and vehicles should be entered at realistic resale value, not purchase price or insured value. The 10% property shock is a simple sensitivity, not a forecast. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Net Worth Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How do I calculate net worth?
Total everything you own at realistic resale value, then subtract every debt. Here $774,400 of assets less $342,500 of liabilities gives $431,900. The arithmetic is trivial; the honesty of the valuations is what makes it useful.
What is liquid net worth and why does it matter?
Cash and taxable investments less non-mortgage debt — $60,400 here against a $431,900 headline. It is what you could actually reach in a crisis, and it explains why households with strong net worth can still face acute cash stress.
Should I include my home?
Yes, at realistic resale value, with the mortgage among the liabilities. But recognise that home equity cannot be spent without selling or borrowing, which is why the engine reports it separately as a share of net worth.
Should I include retirement accounts?
Yes, they are genuinely yours. The engine classifies them as illiquid because accessing them early generally means tax and a penalty, so they contribute to long-term wealth but not to short-term resilience.
How should I value my car?
At what you could sell it for today, not what you paid. Vehicles depreciate steeply, and overstating them is one of the commonest ways a household balance sheet flatters itself.
Is negative net worth a disaster?
Not necessarily. It is normal early in a career with student debt and a new mortgage. What matters is the trajectory — whether the gap is closing year on year — rather than any single reading.
How often should I calculate it?
Quarterly is enough. Monthly readings mostly capture market noise and property estimates you cannot control, which tends to produce either false alarm or false confidence.
What is a good debt-to-asset ratio?
Below 50% is generally comfortable and this household is at 44.2%. Higher is not automatically bad if the debt is low-rate and secured against an appreciating asset, but it does amplify every downturn.
Why does a property fall matter so much?
Because leverage. A 10% fall on a $415,000 home is $41,500 — 9.6% of net worth — since the mortgage does not shrink alongside the valuation. That asymmetry is what makes property concentration risky.
Should I count my pension?
A defined-contribution balance, yes, at its current value. A defined-benefit pension has no balance, though it has real value; most people track it separately rather than attempting to capitalise the income stream.
Does net worth include income?
No. Net worth is a stock measure — a snapshot of position at a point in time — while income is a flow. Two households with identical incomes can have wildly different net worth, which is precisely the point of measuring it.
What about business ownership?
Include a defensible valuation under other assets, but be conservative: private business stakes are illiquid, hard to value and often worth considerably less in a forced sale than in a planned one.
How do I increase net worth fastest?
Increase the gap between income and spending, then direct it consistently. Paying down high-rate debt raises net worth exactly as much as saving the same amount, and does so with a guaranteed return.
Should I include life insurance?
Only the cash surrender value of a whole or universal policy. Term insurance has no cash value and belongs in your protection planning rather than on the balance sheet.
Why separate mortgage debt from other debt?
Because it is matched against the asset it secures and is generally long-dated and low-rate. Credit cards, auto and student loans are callable or short-dated and must be netted against liquid assets, which is how the engine treats them.
Is this net worth calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
